DETAILED DESCRIPTION OF THE DRAWINGS

Referring now in detail to the drawings and, in particular, FIG. 1 shows a perspective view of a shelf unit according to an embodiment of the invention. The shelf unit may include a plurality of brackets 1 for securing the shelf unit to a support (not shown). Bracket 1 may comprise, for example, a knife bracket formed from a steel stamping and powder coated. As shown, bracket 1 may include one or more projections disposed at a rear portion thereof for securing the bracket to a modular support. The bracket projections may be inserted into corresponding apertures provided in a modular support to locate and secure the shelf unit at an appropriate height. Multiple shelf units according to an embodiment of the invention may be secured to a support and positioned one over another in a stacked manner.

A tray 2 extends between the brackets 1. Tray 2 may be formed from any suitable rigid material, for example injection molded acrylonitrile butadiene styrene (ABS) plastic. As shown, tray 2 includes a front portion 3 comprising a plurality of edges 4. Plurality of edges 4 are arranged with adjacent edges 4 disposed at alternating angles to form a sawtooth or zig zag pattern.

A cross-bar 5 may be secured to brackets 1 and disposed over tray 2. Cross-bar 5 may strengthen and provide added rigidity to the shelf unit. Moreover, cross-bar 5 may provide support for a wire grid 6 disposed over tray 2. Wire grid 6 may be secured to brackets 1 and cross-bar 5 as shown. Wire grid 6 may extend from a rear portion of tray 2 to an area just behind front portion 3 of tray 2, thereby covering most of the product units disposed on the shelf unit and leaving only the front-most product or products accessible. In this way, wire grid 6 may serve as a security mechanism by preventing a prospective shoplifter from reaching into the shelf unit from above and removing an entire row or rows of products from the shelf unit.

In an embodiment of the invention, a plurality of shelf units may be secured to a support and stacked one on top of another, leaving only a small vertical spacing between units. An uppermost shelf unit may include wire grid 6 for restricting access to the products disposed on the uppermost shelf unit. The cross-bar 5 disposed over the trays 2 may further provide a security function by preventing the removal of a shelf unit from the support without first removing the unit positioned immediately over the shelf unit sought to be removed. In this way, a prospective shoplifter is unable to remove an entire shelf unit and gain access to the products disposed therein without first removing each shelf unit located over the unit. This feature further restricts access to the products disposed on a shelf unit according to an embodiment of the invention and prevents or reduces the occurrence of theft.

A face portion 7 is disposed over the front portion 3 of the shelf unit. Face portion 7 is configured to conform substantially to the shape of front portion 3 and follows the sawtooth or zig zag pattern formed by edges 4 of tray 2. Face portion 7 may comprise one or more windows 8 arranged so that products disposed on the shelf unit behind the windows 8 may be viewed. Windows 8 may be formed from a transparent or semi-transparent material, for example injection molded clear polycarbonate plastic.

A shelf unit according to an embodiment of the invention further comprises a plurality of adjustable partitions or dividers 9 disposed on tray 2. Partitions or dividers 9 are arranged substantially parallel to brackets 1 and form a plurality of rows defined on one side by partition 9 and on another side by an second partition 9 or bracket 1. Partitions 9 are adjustable so that a width of each individual row may be adjusted to accommodate the dimensions of the product to be housed in the particular row. Adjustable partitions may be configured so that they are free to slide left or right as products are loaded into a row. Such partitions are self-adjusting in that the product finds its proper row width by displacing the flexible partition or partitions. In an additional embodiment, partitions 9 may be locked into a plurality of fixed positions, forming rows of appropriate widths. For example, partitions 9 may snap into place on tray 2. Fixed stops or snaps for locating the partition 9 may be spaced at ½ inch or ¼ inch intervals, thereby allowing for precise positioning of the partition. When a partition is snapped or otherwise secured in place in this embodiment, products in an adjacent row will not encroach or displace the partition.

Each row in the shelf unit according to an embodiment of the invention may further include a biasing mechanism or pusher for biasing the product in that row toward the front of the shelf unit, where the product can be viewed and accessed by purchasers. As shown in FIGS. 2 and 4, the biasing mechanism includes a biasing element 101 and a slidable product advancing member 102. Slidable product advancing member may have a face disposed substantially parallel to the edge 4 at the front of the row wherein the biasing mechanism is disposed, as shown.

Biasing element 101 may comprise a spring element which is secured at one end near a front of the row. In the embodiments shown, biasing element 101 comprises a length of flat metal spring material which is secured at one end near a front of the row and forms a coil which is uncoiled as slidable product advancing member 102 is moved toward a rear of the row. The coiled spring biases the product advancing member 102 toward a front of the shelf unit. Thus, as products are removed from the front of a row of products, the biasing mechanism displaces the remaining row of product toward a front of the shelf unit, thereby maintaining a neat, fully stocked appearance and eliminating the need for manual leveling.

Products may be arranged in the adjacent rows defined by a pair of partitions 9 or a partition 9 and a bracket 1 at alternating angles to form a sawtooth pattern corresponding to the pattern formed by the plurality of edges 4 at the front portion of tray 2. Each row of products forms a non-right angle with respect to bracket 1 with adjacent rows of products angled out from a rear of the shelf unit and in toward a rear of the shelf unit in an alternating manner to form a sawtooth or zig zag pattern.

By arranging the products in rows with adjacent rows disposed at alternating angles, it is possible to fit more products in a given amount of shelf space as compared to conventional arrangements wherein products are arranged in parallel rows at substantially right angles to a shelf bracket. The arrangement of products in a shelf unit according to an embodiment of the invention achieves significant space saving, allowing more products to be stocked in a given amount of shelf space. For example, in the embodiment shown in the drawings, twelve rows of products are arranged on a shelf unit which takes up a linear space which would accommodate only ten rows of the same product if arranged in a conventional manner in parallel rows.

A shelf unit according to an embodiment of the invention may be sized and shaped so that it is suitable for holding a particular product or class of products. For example, the embodiment shown in the drawing figures may be used to display and hold packages of razor blade cartridges in a space-saving manner. The dimensions of the shelf unit can be adapted to accommodate a wide variety of products for retail sale, for example personal care products or any other products which are suitable for displaying on a conventional shelf assemblies.

Face portion 7 of the shelf unit may be secured to tray 2 in a stationary manner, as illustrated in FIGS. 1 and 2, or alternatively may be secured to tray 2 with one or more hinges 71, as illustrated in FIGS. 3 and 4. Hinges 71 allow face 7 to pivot between an open position (as shown in FIGS. 3 and 4) for loading products into the shelf unit and a closed position. A locking mechanism may be provided for locking the drop down face 7 in either an open or closed position. During loading, the drop down hinged face may be moved to the open position so that products may be inserted into appropriate rows of the shelf unit from the front. Following the stocking of the shelf, the face 7 is moved to the closed position. The locking mechanism may be adapted so that face 7 may be locked in place only by authorized persons, for example by a store employee.

As shown in FIGS. 3 and 4, a shelf unit according to an embodiment of the invention may include one or more paddles or stops 22 disposed in one or more of the product rows. Paddles 22 are pivotally mounted to tray 2 and are adapted to pivot downwardly toward a rear of the shelf unit as products are loaded into the respective row. Paddles 22 are biased in a upward position, for example with a spring mechanism, so that paddles 22 return to a vertical position when no longer held down by a product.

Paddles 22 assist in front loading of the shelf unit by allowing a plurality of products to be loaded at one time, rather than loading just a single unit at a time. As products are placed into a particular row, the paddle 22 pivot down toward a rear of the shelf unit and the products push against the biasing mechanism or pusher, displacing it toward the rear of the shelf unit. Once the row of products is pushed past the paddle 22, the paddle 22 flips up into its vertical state and acts as a stop, preventing the biasing mechanism from pushing the row of products all the way to the front of the shelf unit. This feature facilitates the loading of a plurality of product units into the shelf unit, and allows for more efficient stocking of the shelf unit.

As shown in FIGS. 1 and 2, a shelf unit according to an embodiment of the invention may include one or more apertures 81 to facilitate loading of products into the shelf unit.
